AUTOMATIC REGiSTER FOR PRENTlNC FRAMES.

SPECIFICATION forming part of Letters Patent No, 582,376, dated May 1 1,1897.

Application filed December 28, 1896. serial No. (317,248. (No model.)

To (LZZ whom it Hui/y OOH/GUIL-"LJ Be it known that I, STEPHEN H.SECKNER, a citizen of the United States, residing at Fort Collins, inthe county of Larimer and State of Colorado, have invented a new anduseful Automatic Register for Printing-Frames, of which the following isa specification.

This invention relates to improvements in automatic registers forprintingframes used by photographers, draftsmen, and others in printingcopies of photographs, drawings, and the like; and the inventionconsists in the several details of construction and combina tion ofparts hereinafter fully described, and particularly pointed out in theclaims.

In the drawings, Figure 1 is a plan of a printing-frame with myautomatic register attached thereto. Fig. 2 is a side view of theregister, the printing-frame being shown in section. Fig. 3 is a View inperspective of a part of the register detached.

Similar numerals of reference designate corresponding parts in theseveral figures of the drawings.

1 represents the frame; 2 and 3, the shutters, hinged together, and atthe pressuresprings. These are of the ordinary construction.

5 represents a plate provided with clips (I, which plate is adapted tofit over the spring 4:, which looks the shutter 3, the plate portionengaging the under surface of the spring.

7 represents a registeringdisk provided with a series of teeth 8 on itsperiphery, which teeth have each a numeral. The disk may be providedwith any number of teeth, but ordinarily twelve is the preferred number,and they are numbered in sequence, as shown in the drawings.

The disk 7 is centrally pivoted on the shutter 3 by means of a pin 9,and preferably a metal plate 10 is interposed between it and the shutterto prevent wear on the latter. As shown in the drawings, the diskextends partially under the spring 4: when the latter is in its lockedposition.

11 represents a lever pivoted at one end on the pin 9 and extendingoutwardly beyond the disk. Just beyond the periphery of the disk thelever is bent upwardly to form a vertical portion 12 and then outwardlyto form the horizontal portion 13, substantially parallel with the mainpart of the lever. From the vertical part 12 of the lever a springpawl1e extends rearwardly and is curved to engage the teeth 8 of theregistering-disk 7. T 1e plate 5 is provided with a lug 15, to which ispivoted one end of a link 16, the other end of this link being pivotallyconnected to the horizontal portion 13 of the lever 11.

17 represents a plate secured on the shutter 3 and carrying a springlocking-dog 18, the end of which is in engagement with the teeth of theregistering-disk.

19 represents a staple secured in the shutter 3 and extending over thespringarm +1: for the purpose of limiting its lateral movement, thislimitation being necessaryin order to prevent the registering-disk beingturned more than one teeth at a time.

Preferably the lever 11 is of spring metal to permit it to yield andaccommodate itself to the vertical movement of the spring-arm a, whichis necessary in the locking and unlocking thereof.

The operation of the device will be readily understood from theforegoing description, and it is evident that when the spring a isturned on its pivot in the direction of the arrow the spring-pawl 11-will cause the registering-disk to turn to the extent of one tooth andthat in its backward movement the dog 18 will prevent any backwardmovement of the registering-disk. Every time, therefore, that the spring4 on the shutter 3 is unlocked it will be registered by the disk, and asin operation it will only be necessary to unlock this lever when a printis removed it is evident that an accurate register of the number ofprints will be kept. By opening the shut ter 2 the print can beinspected without removing it from the frame and without interferingwith the registering device.

It will be apparent that changes in the form, proportion, and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of: theadvantages of this invention.

It is evident that my registering device can be readily attached toprintingframes now in use without mutilating them in any manner ornecessitating any change in their structure, for the plate 5 can beeasily attached to the spring-arm and the other portions readilyattached to the shutter.

Having thus described the invention,what is claimed as new is 1. In aprinting-frame, the combination with a shutter and its locking-spring,of a registering-disk pivoted on the shutter and provided with a seriesof numbered peripheral teeth, a lever pivoted on the shutter andprovided with a spring-pawl to engage the teeth of said disk, and a linkconnected at one end to the locking-spring and at its other end to thefree end of the lever, substantially as described.

2. In a printing-frame, the combination with a shutter and itslocking-spring, of a registering-disk pivotally mounted on a pin securedin the shutter, said disk having; a series of numbered peripheral teeth,a lever pivoted at one end on said pin below the disk and provided atits free end with a springpawl to engage the teeth of the disk, a linkconnected at one end to the locking-spring and at its other end to thefree end of the lever, a spring-dog secured at one end to theshutter-frame with its free end engaging the teeth of the disk, and adevice to limit the movement of the locking-spring,substantially asdescribed.

3. In a printing-frame, the combination with a shutter and itslocking-spring, of a registering-disk pivoted on the shutter andprovided with a series of numbered peripheral teeth, a lever pivoted onthe shutter and provided with a spring-pawl to engage the teeth of thedisk, a plate secured to the under side of the spring and provided witha lug, a link connected at one end to said lug and at its other end tothe free end of the lever, a spring-dog to prevent backward movement ofthe disk, and a device to limit the movement of the locking-spring,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
